Description

Method for manufacturing a bearing assembly
Technical Field
The present invention relates to a method of manufacturing a bearing assembly for mounting a control shaft. The invention further relates to a bearing assembly manufactured by the method and to a method of manufacturing a control shaft using such a bearing assembly.
Background
The production of camshafts or control shafts is usually carried out primarily by joining separate components, such as bearings and cams, to the camshaft, which is then ground, in particular in the region of the cams, and is therefore finished. In particular, during this polishing treatment by grinding, grinding dust is generated which can penetrate into the bearing, in particular into the bearing surface, and settle there, and can lead to increased wear during the subsequent operation of the internal combustion engine equipped with the camshaft, and in the most harmful case even to damage of the bearing. For this reason, it is known to protect bearings, such as roller bearings or needle bearings, from contamination during grinding of the cams by manually applied cages. However, these cages have to be laboriously screwed down manually and loosened again after the actual grinding process, which is both time-consuming and costly.
Disclosure of Invention
The present invention therefore concerns the following problems: a method for manufacturing a control shaft is provided that overcomes the drawbacks known in the prior art.
According to the invention, this problem is solved by the subject matter of the independent claims. Advantageous embodiments are the subject of the dependent claims.
The invention is based on the following main concepts: first a prefabricated bearing assembly is manufactured, which has been protected by a contracted telescopic hose or a wound membrane tape in a way that can be used in a prefabricated state during the manufacture of the control shaft, without an additional (dust) cage, since the telescopic hose or the membrane tape protects the bearing arrangement from any grinding dust/grinding sludge/grinding particles that may occur. In the method for manufacturing a bearing assembly according to the invention, the bearing is first prepared or manufactured, for example by mounting a roller body in a bearing ring. The bearing is then pushed onto the assembly mandrel together with the two rings arranged on the front side, in particular plastic or metal rings. The two rings are thereby pretensioned against the front side, i.e. the axial front side, of the bearing. The bellows is now pushed over the bearing and the two rings and shrunk thereon by heating. Alternatively to this, the film strip can also be wound around the bearing and the two rings. Subsequently, the bearing assembly thus prefabricated and held together by the contracted bellows or wound film strip can be withdrawn from the assembly mandrel and fed to further manufacture of the control shaft. The prefabricated bearing assembly is reserved for the manufacture of the control shaft, whereby the hitherto very complicated manufacturing process can be simplified at least somewhat.
The invention is also based on the following main concepts: the bearing assembly manufactured according to the previously described method is now arranged on a corresponding control shaft/camshaft with at least one control element/cam, which is for example thermally bonded, whereas at least one prefabricated bearing assembly is merely pushed onto the control shaft and fixed by means of two rings. In the next process step, the cam or the control element can now be ground without the grinding dust or grinding sludge that has in this case penetrated into the bearing, i.e. into the bearing assembly (component) and lead to undesired contamination. Once the grinding process is completed, the telescopic hose or the film strip on at least one bearing assembly is removed, for example by pulling a tear-off tab which tears off the telescopic hose along a weakening of the material, for example a perforation, and thus makes its removal easier. The film strip can simply be unwound. In the method according to the invention for producing a control shaft, in particular the hitherto necessary, laborious and therefore costly mounting of the protective cage on the respective bearing can be dispensed with, as a result of which not only the production process is significantly simplified, but also a significantly more cost-effective process is possible. When the camshaft according to the invention is mounted in a cylinder head cover or cylinder head of an internal combustion engine, it is displaced and advanced a few tenths of a millimeter, for example about 0.6mm in the axial direction, before reaching the final mounting end position, so that at least a slight spacing between the bearing and the two rings arranged on its front side is achieved and thus a gap is made possible. Of course, not only cams per se, but also eccentric discs with at least one bearing assembly, sensors, signal generators or other components can be slid onto the control shaft/camshaft according to the invention.
The invention is also based on the following main concepts: the bearing assembly produced according to the method is firstly prefabricated in a separate production step and therefore the installation of the assembled control shaft can be made simpler and in particular more flexible. As already mentioned initially, the telescopic hose can in this case comprise a tear-off tab, by means of which the telescopic hose can be torn off and thus easily removed by applying a corresponding pulling force. In order to simplify the tearing off and removal of the bellows, this can have material weakening, for example perforations, with the result that a desired tear-off point is created which is relatively simple and cost-effective. The material weakening can of course also be produced by cutting out with a line, shearing or by laser, as a result of which not only a high quality but also a cost-effective production of such a material weakening is possible.
In a further advantageous embodiment of the solution according to the invention, the ring has a smaller outer diameter than the bearing, whereby it can be ensured that the ring is dedicated to the axial fixing of the bearing on the control shaft, but does not come into contact with, for example, the cylinder head or the bearing seat of the cylinder head cover.
In a further advantageous embodiment of the bearing assembly according to the invention, provision is made for the telescopic hose to have a greater axial length than the bearing assembly and, as a result, to enclose the two rings of the front side at the longitudinal end sides in the retracted state and thus to hold the entire bearing assembly together. As a result, it is possible to create a bearing assembly which is not only compact but also very stable, without having separate components such as, for example, two rings and bearings which need to be additionally fixed to one another.
In a further advantageous embodiment of the solution according to the invention, the ring has a front side oil feed structure, in particular a groove, slot, web or hemispherical elevation. After the bearing assembly is mounted on the control shaft, the control shaft is displaced in the axial direction and/or slightly backwards, as a result of which at least a small axial gap is formed between the bearing and the two rings arranged on the front side of the permissible gap. At least on the front side facing the bearing, the ring has the previously described oil feed structure, which allows a continuous oil supply, for example, usually lubricating oil, into the bearing during operation of the internal combustion engine and thereby ensures reliable lubrication of the roller bearing and, in addition, enables a smooth-running mounting of the camshaft for a long period of time.
Further important features and advantages of the invention will be obtained from the dependent claims, the figures and the associated description of the figures with reference to the figures.
It is understood that the aforementioned features, as well as those which remain described below, can be used not only in the respectively given combination, but also in other combinations or alone, without departing from the framework of the present invention.

Detailed Description
According to fig. 1, in a method according to the invention for producing a bearing assembly 1, by means of which bearing assembly 1, subsequently for example a control shaft/camshaft 2, is mounted in a cylinder head 3 or a cylinder head cover 4 (see fig. 4), a bearing 5 is first prepared or produced by mounting or arranging a roller body 6 in a bearing ring 7. The term "control shaft" is in the following often equivalent to the term "camshaft". The roller body 6 can in this case be configured as a roller or needle roller and a ball. The bearing 5 with the two rings 8 arranged on its front side, in particular with plastic or metal rings, is then pushed onto an assembly mandrel 9 (see fig. 1), where the two rings 9 are pretensioned towards the front side of the bearing 5 by a corresponding sleeve 10. This is caused by the sleeve 10 being pressed onto the upper ring 8 and the lower ring 8 resting on a support or stop 11 of the assembly mandrel 9. The bellows 12 is then pushed over the bearing 5 and the two rings 8 and shrunk on these by heating. Alternatively, the film strip 12' can also be wound around the bearing 5 and the two rings 8. The film strip 12' is thus wound under tension and partially overlaps the bearing 5 and the two rings 8, ensuring tightness.
Fig. 1 shows the bellows 12 before heating, while fig. 2 and 3 show the bellows 12 after shrinking onto the rings 8 and the bearings 5, or after the film strip 12' is wound under tension around the bearings 5 and the two rings 8. This is wound in a partially overlapping manner, so that gaps can be avoided and a tight packing of the bearing 5 and the ring 8 can be ensured. The bearing assembly 1 thus prefabricated can now be removed from the assembly mandrel 9. As can be inferred from fig. 1, the bracket 11 or the stop 11 has the following effect: the bellows 12 can be pushed further downwards on the front side, so that, for example, the ring 8 can be enclosed by the bellows 12 on the front side. The ring 8 can in this case have a radially outer configuration at least in the overlapping region of the bellows 12. According to fig. 2 and 3, the bellows 12 therefore does not, however, enclose the front sides of the two rings, but merely holds these on its outer lateral surfaces.
The bearing assembly 1 according to the invention thus consists of the actual bearing 5, the bearing ring 7 and the roller body 6 mounted therein, the two rings 8 arranged on the front side thereof and the telescopic hose 12 which is shrunk onto it and fixes the two rings 8 on the bearing 5.
The contracted bellows 12 or the wrapped film strip 12' protects the bearing 5 from penetrating abrasive particles and thus from any consequent damage during the grinding of the cam 13. A tear tab (tear tab)14, for example, can be provided on the telescoping hose 12, which makes tearing off easier and thus removes the telescoping hose 12 from the bearing assembly 1 after grinding. The film strip 12' can be easily wound. The telescopic hose 12 can further have a material weakening, for example in the form of a perforation, which additionally simplifies the removal of the telescopic hose 12 after the grinding of the cam 13. The bellows 12 or the film strip 12' can also have a layer, in particular an adhesive layer, which at least partially increases the sealing effect from the inside.
The bearing assembly 1 according to the invention, which is usually prefabricated separately, is now slid onto the control shaft 15 during assembly of the control shaft/camshaft 2 by means of at least one control element, in particular the cam 13, it being clear of course here that not only one bearing assembly 1 and control element/cam 13 is slid onto the control shaft 15, but a plurality of bearing assemblies 1 and control elements/cams 13 are slid onto the control shaft 15 in each case. When the bearing assembly 1 is pushed onto the control shaft 15 and the control member, in particular when the cam 13 is bonded to the control shaft 15, for example by a shrink fit, the post-treatment or polishing of the control member/cam 13 can be done in particular by grinding. The bearing assembly 8 is retained on the control shaft 15. When the finishing is done, for example, by grinding the cams 13, the camshaft 2 can be cleaned and the bellows 12 or the film strip 12' can be opened and removed from the respective bearing assembly 1, for example, by a tear on the tear tab 14, and the prefabricated camshaft 2 can be inserted into the cylinder head 3 or cylinder head cover 4.
Before reaching the end position of the camshaft 2 in the cylinder head 3 or cylinder head cover 4, the control shaft 15 is moved and is slightly set back in the axial direction relative to the bearing 5, and thus a minimum distance 17 in the axial direction between the two rings 18 and the bearing 5 is created, so that a clearance of the bearing 5 can be created.
The bearing 5 of the control shaft 2 can be fixed axially to create a gap before insertion into the cylinder head 3, typically after removal of the bellows 12 or the film strip 12', and the control shaft 2 is preferably displaced axially by at least 1/10mm as shown in fig. 5. For this purpose, an axial force is exerted on the control shaft 2 and at the same time the bearing 5 is held by the holding profile 23.
In order to reliably ensure the lubrication of the bearing 5 during operation of the control shaft 2 mounted in the internal combustion engine 8, an oil feed structure or oil feed structure 20 (see detail from fig. 3), in particular a groove, slot, web or hemispherical elevation 22, can be provided on one front side 19 of the two rings 8 facing the bearing ring 7, which enables reliable transport of oil into the region between the roller body 6 and the control shaft 15 and thus on the one hand reliable lubrication of the bearing 5 and on the other hand smooth-running mounting of the control shaft 2.
If fig. 1 to 4 are viewed here, it can be seen that the ring 8 has a smaller outer diameter than the ring 7, as a result of which a simplified insertion of the control shaft 2 into the associated bearing opening 21 of the cylinder head 3 or of the cylinder head cover 4 is possible.
Using the method according to the invention for producing the bearing assembly 1 according to the invention and using the resulting method according to the invention for producing the control shaft 2, the latter can be produced in a significantly simple and cost-effective manner, since the laborious covering of the bearing 5, in particular during the grinding of the control element (in particular the cam 13), is omitted. Conversely, the bearing 5 is protected against any undesired ingress of grinding dust by the two rings 8 arranged on its front side and the bellows 12 shrunk thereon or the film strip 12' wound thereon. This can be removed considerably more easily than the protective cages known hitherto from the prior art, for example by simple tearing off or uncoiling.
